What About Brewed Coffee
So lets say youve brewed a batch of coffee. Once its been brewed, coffee is usually only good for about 4-6 hours. Its still safe to drink, but the flavor wont be as satisfying as when it was freshly made. Because water helps release the solubles in coffee, your cup of coffee can oxidize much faster in liquid form than in solid form. So to play it safe, your absolute maximum limit to brewed coffee should be no longer than 8 hours, and thats only if youre desperate for a caffeine fix.
Another thing that we dont recommend is the re-heating of already cooled coffee. Once the coffee has been brewed, most of the flavor has already been extracted. Re-heating coffee can further extract or break down the flavor and oils in the coffee, causing it to have an altered taste. One trick to prevent you from re-heating coffee is investing in a thermos or an Ember Cup to make sure your coffee stays warm for up to a couple of hours after brewing.
One tip to save leftover brewed coffee is by freezing it for future use. My pouring leftover coffee into a couple of ice trays in your freezer and you can sue them in the future for smoothies, ice cream, or even to keep iced coffee cold.
The Risk If Consuming An Expired Roasted Coffee Bean
All coffee, regardless of whether its grounded up or as a whole bean, must expire ultimately. But it might be moderately sad for the coffee lovers out here, the degradation of coffee is practically inevitable.
There are many causes why coffee gets bad, and there are additionally different circumstances that might even make it rot even quicker than its expected expiration date. These circumstances constitute the class the coffee is in, how it would be roasted and stored.
If you happened to have consumed spoilt coffee, the good news is you are likely not to get sick. Nevertheless, if the coffee had mildew or mold, you need not use it.
You will also notice that the flavor and taste of the bean is different. Most often if you take in spoiled coffee, you may experience digestive problems, frequent urge to go to the washrooms, general body fatigue etc.
How To Find A Fresh Bag Of Roasted Coffee Beans
If you are not roasting the coffee beans yourself, there are a few things you need to consider.
The best way to tell which package of coffee beans is fresh and which are not is by checking the roasting date, which should be marked on the package. Make sure you get beans that have been roasted within the previous three weeks. Avoid the ones that are older because they will not have peak aroma and flavor.

Is It Possible For Coffee Beans To Go Bad
We’ve all had a cup of coffee that hasn’t tasted or smelled good, and this can be down to a number of reasons, like flavor, roasting procedure, and even the expiration date. More often than not, its thanks to the bean quality. If you look after your coffee beans properly, then there is no reason why they should go bad. However, failing to store coffee beans correctly, can result in their freshness being drastically affected.
Some telltale signs of stale coffee beans are if they look bad, or smell different. If they start to develop a bit of a moldy or putrid scent, then it’s best to throw them in the trash and get yourself a new bag. When coffee beans are roasted, gases, like carbon dioxide form inside of them, and then start to leave the beans a few days after the roasting process is finished. When carbon dioxide leaves beans too quickly, this may affect their taste, and make them stale.
If instead of a really foul smell, your coffee simply has a dull aroma, then it’s a good idea to avoid using them. The smell and taste of coffee are interlinked, and if your beans have lost that enticing aroma, then it’s safe to say that they may have passed their peak.
If you accidentally drink some coffee that you think might have been made with expired beans, don’t panic! Although the flavor will be a little disappointing, you won’t get sick from drinking coffee made with out-of-date beans.
Oxidation And Roasted On Date Are Good Markers Of Freshness
I said there are a few markers you an use to see if your coffee is still fresh. Well, you’ll notice first by the roasted on date. All that is is the date the beans have been roasted on, and then sealed into their bag.
If you manage to get your hands on a fresh bag it will be good for up to 2-3 days after roasting. The aroma will start to degrade much faster after those weeks. However if you’ve got a an unopened bag that’s been nitrogen flushed, the roasted on date is not relevant.
Nitrogen flushing removes the oxygen from the equation, and keeps the coffee beans on a sort of ‘pause’ button. The moment you open the bag for the first time, those 2-3 weeks start ticking.
Now, oxidation is something that is very hard to avoid. We are literally surrounded by air. But you can reduce the amount of exposure to air by keeping your beans in an airtight container, and keep it in a cool, dry place.
Still not very sure ? If you’re willing to try a batch of coffee to see if it’s still good, you can try grinding some beans for one cup. Grind them to whatever size you like for a filter coffee. Then, when you slowly pour the hot water over the filter with the coffee grounds in it, you should see some bubbles.
There should be a nice, thick foam on top, and some actual air bubble coming up and through the coffee grounds. If there is none of that happening, your coffee is unfortunately gone.

Extending The Shelf Life Of Roasted Coffee Beans
If you dont think youll finish your coffee before it starts to go off you can consider a number of things that will help to extend its shelf life. The reason why coffee goes off is mainly because the oils start to evaporate. As with other food stuff, this happens quicker with a larger surface area, so ground coffee will start to spoil a lot sooner than the whole bean. Because of this, it is better to only grind the beans when you want to use them, rather than doing them all at once.
The best way to extend the life of your coffee, no matter its state, is by putting it in the freezer. This wont actually freeze it, so it will be ready to use straight away after taking out, but the colder temperatures prevent the evaporation.

Keep The Beans Cool And Airtight
As we mentioned before, air, moisture, and extreme heat and light are your coffees greatest enemies.
To keep your whole coffee beans roasted flavor fresh for longer, store them in an opaque and airtight container at room temperature. Also, avoid using clear containers as they will allow in the light that will compromise the flavor of your coffee.
Additionally, keep your coffee beans away from hot spots in your kitchen. These could be near an oven or a kitchen corner that gets too much sunlight and heat.
Although sufficient for a while, the retail packaging of your coffee isnt ideal for long-term storage. If possible, you should consider buying special storage containers that have an airtight seal.
The Shelf Life Of Roasted Coffee Beans
Roasted coffee beans behave differently when stored than raw beans. Heat treatment not only changes the color, smell, taste and even the size of the coffee bean but also reveals caffeine a bouquet of aromatic oils that evaporate very quickly. The shelf life of the roasted beans varies greatly depending on the storage conditions.
Processed beans that are stored in ordinary, leaky containers jars or boxes have a shelf life of 10-14 days.
Packaging at home using foil will extend the shelf life up to 3-4 weeks.
Roasted beans packed in sealed four-layer paper bags are stored for up to 6 months. If the bags have an additional polymer coating from the inside, then the period increases to 9 months.
Roasted coffee beans in heat-sealable bags based on film or foil can be stored for up to 12 months. Such bags have a special vent valve. It is necessary for freshly roasted beans because after roasting, they continue to emit carbon dioxide due to the opening of the smallest internal capsules. If you let the beans exhale completely, they will undergo strong oxidation.
The presence of a degassing check valve on the bags gives the bean the opportunity to breathe. They can be packaged immediately after processing, and gas will continue to exist without inflating the bag from the inside.
Roasted beans in opaque jars with hermetically sealed lids, packed in a factory way, also have a long shelf life of up to 18 months.

Does Coffee Have A Different Smell When Stale
While there may not be a definitive scent once grounds have oxidized to the point of staleness, its the lack of that distinct and potent aroma coffee has which will tell you whether or not yours has sat for too long.
In the case of instant coffee, which is extracted coffee that has been spray-dried or freeze-dried to increase shelf stability , it may taste like its stale due to the oily flavor components being damaged during processing.
Even when stored properly, the true shelf life of coffee is remarkably short when you follow expert opinion on the matter. However, few retail stores will throw away inventory if its not technically beyond the expiration date.
If you find yourself with coffee that is too stale to brew or past its expiration date or best before date, check out our ideas at the end of this article for how to use them outside of the kitchen.
Whats The Shelf Life And Proper Storage Of Roasted Whole Coffee Beans
Once roasted, coffee beans start to oxidize at a higher pace and therefore lose their flavor and aroma much faster compared to green beans.
Furthermore, as mentioned earlier, the darker the roast the faster the coffee loses its freshness and starts to develop off-flavors.
This causes it to crack.
If you roast your coffee for too long to a dark roast, the pressure inside would push the coffee oils to the surface.
Because of that, and because theyre more porous, dark roasted coffee beans are easier to extract compared to light roasts.
Naturally, for the very same reasons, dark roasts oxidize faster and their flavors and freshness dont last for as long as those of lighter roasts.
To get a better understanding of the shelf life of roasted coffee under different storage conditions, we need to shed light on the process of coffee degassing.
These reactions lead to the generation of gases mostly carbon dioxide .
After roasting is complete, part of the gases remains in the porous structure of the roasted coffee beans. When freshly roasted, the coffee beans still release CO2 .
Degassing may negatively affect coffee extraction if you grind and use the beans right after theyre roasted.
In the first few days after roasting, coffee beans release gases more rapidly.
While brewing, the CO2 gases exit the freshly roasted grounds, forming bubbles.
Those bubbles can disrupt the contact between ground beans and water, thus leading to uneven extraction.
It means theyre still fresh.
Does Coffee Go Bad How To Preserve Its Freshness For An Extended Period
Roasted quality coffee starts to lose its freshness with exposure to air. Seek to order smaller quantities of pure roasted coffee more regularly- sufficient for two weeks or up to a month supply.
Exposure to the atmosphere is damaging for the roasted beans. If you fancy keeping your beans in an open and/or beautiful tin it might be a beneficial idea to apportion your coffee rations into individual smaller servings, with the more substantial, unused serving in an air-tight tin.
This is exceptionally essential when pre-ordering ungrounded coffee, due to the extended susceptibility to air. If you order whole beans, crush the quantity you want immediately and then brew it.
Storing Coffee Beans In A Canister Or Jar
Jars are very popular options for storing whole coffee beans. Given the popularity of this method, you can get jars specifically built to store coffee beans. For their part, the canisters are mostly airtight and opaque. This blocks oxidation as well as changes due to light. Some canisters also include options that make degassing easier.
For your part, remember to keep the jar in a cool and dry place. While the jars are built to store beans in the best possible way, they cant really provide a temperature-controlled environment for the coffee beans! That parts up to you.

What Containers Can I Store Coffee In
If keeping coffee bags in your pantry has been taking up too much space, there are other options for you to utilize. We recommend using storage methods like vacuum-sealed bags or coffee vaults. A vacuum-sealed bag is a literal airtight container that will help you store coffee with minimal risk of oxygen and moisture slipping in.
On the other hand, coffee vaults are normally made out of stainless steel and are specially designed just for storing coffee beans and ground coffee. Most have built-on lids attached to them to make sure that they are as sealed as possible.
